Boot problems after installing LM 18 over Windows7.

[andrewgouw]

I have just installed LM 18 over Windows 7. By that I mean Windows 7 was installed on the hard drive and I had LM 18 installed replacing and overwriting everything on that drive. Installation was successful. However at start-up it tried to boot from Windows which it cannot find. I had to try rebooting several time when it eventualy started up with the boot menu and Windows is still a choice.
ow do I correct this that it just boot to LM with or without the boot menu? Any help?

Here is what the boot/grub/grub.cfg contains:

it does seem to be still chainloading win-7 in that menu,

so - from a Mint Terminal, try typing

Code: Select all

sudo update-grub

then re-boot the machine & see if there is any difference,
in the Menu

[andrewgouw]

I have done as you suggested "sudo update-grub". It is still doing the same thing , it is trying to boot to Windows7.

I was able to resolve this problem by commenting out this whole section in /boot/grub/grub.cfg
